T0 aZZ whom it may concern:

Be-it known that I, JOHN F. NEWMAN, a. citizen of the United States,residing at Kansas City, in the county of J ackson"and State ofMissouri, have invented a new and usefnl Hoe, of which' the. followingis a specification The device forming the subject matter of thisapplicati'on is a hoe, and the invention aims to provide 21 hoe whichwill scour itself readily, the blade of the hoe being sharpened alongits lower edge and at its ends, the 'construction being such that theblade may be sharpened .as aforesaid,without rexidering unduly-brittle,the connection between the blade of the hoe and the shank thereof.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of thattype. to which the -inventionappertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the-combinatien andarrangement of parts and in the details of constrction hereinafterdescribed and claimed, it being nderstood that, within the scope of whatis claimed, changes in the precise -embodinient of the invention showncan be made without departing from the spirit of the invention.

In the accompanying' draw1ngsz- Figure 1 shows in side elevation, 2 hoeconstructed in accordance withthe inventien; Fig. 2 is 3, top plan; Fig.3 is an end elevation; and Fig. 4 isa sect1on taken upproximately on theline 4-4= of Fig. 3.

The hoe hereinafter claimed. com rises & blade 1 which preferably ismade 0. tool steel. The numeral 2 den0tes 1 shank mounted in a handle30, the shank 2 being formeel integrally with the blade 1 and beinlocated in direct alinement therewith. It 1s to be observed that theconstruction last aboyge described is such that there are 110roject-ions on either the front surfae' of the blade 1 or on the rearsurface thereof, as 1s the case when the shank 2 is overlapped on theblade and is secured threto by nveting or otherwise.. The advantage inhaving no pr0ections on either the front orthe rear sur ace of a hoe blade will be apprecmted readly by any erson who has us'ed ;1 toolof thekind allud ed to. In order to provide cutting edge, en

a secure connection betwen the blade 1 and the shank 2, s1nce the shankis not overlapped on the blade, the shank is increased in width, asindicated at 5, at the place vhere the shank is att'ached to the bladeThe blade 1 tapers in thickness, as indicated at 6, from its centralportion to its ends, to define terminal cutting edges 7. In crosssect1on, the blade 1 is wedge-shaped as indi cated at 8, to define alower cutting edge 9. The blade 1 is tempered along its ends -and in itslower. portion, whereby the edges 7 and 9 wil] hold their sharpness.WVithin an area defined by the line 10 in Fig. 3 and b a port1on of theupper edge 11 of the b ade 1, the blade is not tempered. The blade,thereforeis untempered at the 1ace of juncture between the shank 2 enthe blade. As a consequence, there is a mass of tough metal where theshank 2 joins the blade 1, and a fracture at this point will jectingfrom the blade in direct alinement therewith,. the blade being, in theform of a. narrow strip of relatively small width meesuredlongitudinally of the shank and being of relatively great lengthmeasured transversely of theshank, the shank being increased in widthatthe placewhere it joins the blade, the blade tapering in thickness fi0lnits central portion te its ends to define terminal. cutting edgesandbeing wedgesh aped in cross section, to define a 1ower .cuttin edge,the blade being tapered along its en s and in itslower portion, Wh'erebysaid edges will holdtheir sharpness the blade embodying en imtemperedportion located atthe place of juncture between the shank and thebladean d extended well towerd the ends ofthe b1edeto prevent s
